# Is it Profitable to Sublet a Rental Property? *Nora Nyström* *27 maj 2026* > Subletting your apartment can be a way to earn extra income, but is it truly profitable to sublet second hand? We analyze the financial aspects, tax rules, and legalities surrounding second-hand rentals. Considering whether it's profitable to sublet second hand is a smart move for many tenants who have an attractive dwelling. Whether it's about covering your own living costs during a period of absence or generating extra income, there are several factors to weigh. This article delves into the financial conditions, tax implications, and legal frameworks governing second-hand rentals in Sweden to give you a clear picture of whether it's profitable to sublet second hand. ## Potential Income and Costs The most obvious question is how much money you can actually earn. The rent you can charge for a second-hand rental is partly regulated. For it to be profitable to sublet second hand, you need to cover your own housing costs (rent to the landlord, electricity, broadband, etc.) and ideally have a surplus left over. You are not allowed to charge a rent higher than your own, plus a surcharge for furnishings and utilities if you are renting out a furnished property. This surcharge is generally limited, so it's important to understand the rules to avoid problems. ### Calculating Your Potential Income To calculate your potential second-hand income, start by summing up your own monthly costs for the dwelling. Then, add a reasonable surcharge for furniture and any utilities. Compare this with what the market is willing to pay for a similar dwelling in your area. Remember that the Rent Tribunal can review the rent if it is deemed unreasonable. ## Tax Implications of Second-Hand Rentals One of the most crucial aspects to understand is how taxes affect your profit. When you sublet part of your dwelling, or the entire dwelling, it is considered income. For it to be clearly profitable to sublet second hand, you must be aware of how taxation works. ### How is the Income Taxed? Income from second-hand rentals is taxed as capital income. You are allowed to make a standard deduction. For renting out an entire property (e.g., an apartment or a house), you can deduct SEK 40,000 per year. Additionally, you can deduct 20 percent of the rental income exceeding SEK 40,000. If you are renting out a room, the rules are different; the entire rental income is tax-free up to SEK 40,000 per year, and 20 percent of the amount above that is taxable. Therefore, it's important to know which category your rental falls into to correctly calculate your tax on renting out. ### Important to Declare All rental income must be declared. Failure to declare can lead to fines or tax surcharges. Ensure you have all documentation ready when it's time for tax filing. ## Legal Aspects and Permits Before even considering subletting, it is crucial to understand the legal requirements and obtain the necessary permits. Renting out without permission can have serious consequences. ### Permission from the Landlord In most cases, permission from your landlord (housing association or municipal company) is required to sublet your dwelling. The application for permission must be made in writing, stating the reasons for the subletting (e.g., studies, work in another city, illness). The landlord may only refuse if there is reason to believe that the subletting will not be managed correctly, or if there are other justifiable reasons. Not having permission can lead to the termination of your own rental contract. ### Rental Contract for Second-Hand Rentals It is important to establish a written second-hand agreement between you as the primary tenant and your subtenant. This agreement should clearly outline the rental period, rent amount, termination conditions, and other relevant points. This protects both you and your subtenant and reduces the risk of future disputes. These rules for second-hand rentals are in place to ensure security for all parties. ### Tenant Rights During Renovations (and How It Affects Subletting) While not directly related to profitability, ongoing renovations in the building can affect your ability to sublet or the attractiveness of the property to a subtenant. Tenants have certain rights during renovations that may cause disturbances. As the primary tenant, it is your responsibility to inform your subtenant about any potential disruptions. ## Is it Profitable to Sublet Second Hand – A Summary So, is it profitable to sublet second hand? The answer is that it can be, but it requires careful planning and an understanding of all the rules involved. To maximize your profit and minimize risks, you should: * **Check permit rules:** Ensure you have the landlord's approval. * **Understand rent regulations:** Do not charge excessive rent. * **Grasp tax rules:** Declare correctly to avoid issues. * **Establish a clear contract:** Protect yourself and your subtenant. By following these steps, you can increase the chances of your second-hand rental being both profitable and trouble-free. Remember that while it can provide good extra income, it's crucial to follow all rules for second-hand rentals. ### FAQ: Common Questions About Subletting ### What is the maximum rent I can charge? You cannot charge rent higher than your own rent plus a reasonable surcharge for furniture and utilities if the dwelling is furnished.
